    Abstract: In a refrigerant circuit (20), a refrigerator circuit (110) and a freezing circuit (30) are connected in parallel to an outdoor circuit (40). In the freezing circuit (30), a freezer circuit (130) and a booster circuit (140) are connected in series. A booster compressor (141) and a four-way switch valve (142) are provided in the booster circuit (140). During the time when a freezer heat exchanger (131) performs cooling operation for cooling the inside air, refrigerant evaporated in the freezer heat exchanger (131) is compressed in the booster compressor (141), and then, is sucked into a variable capacitance compressor (41). On the other hand, during defrosting of the freezer heat exchanger (131), the refrigerant evaporated in a refrigerator heat exchanger (111) is compressed in the booster compressor (141), and then, is supplied to the freezer heat exchanger (131). The refrigerant condensed in the freezer heat exchanger (131) during the defrosting operation is sent back to the refrigerator heat exchanger (111).

    Abstract: The present invention provides an air-condition heat pump capable of defrosting and air-conditioning at same time. The present invention utilizes at least two evaporators, which harvest the energy from one working evaporator to provide energy for defrost operation of another evaporator, thus the air-condition heat pump can defrost without additional energy. Under low temperature working condition, the present invention utilizes a suction pressure boost to increase efficiency.

    Abstract: When a defrosting requiring signal is outputted, the opening of a motor-operated expansion valve (5) is fully closed in a heating cycle so that refrigerant is recovered into a receiver (4). In addition, when the defrosting requiring signal is outputted, an indoor fan (6f) is deactivated so that heat is stored. Further, when the completion of the recovery of refrigerant is determined, defrosting operation is executed. The recovery of refrigerant is completed when an outdoor heat-exchange temperature Tc at the present time drops to or below a specified temperature, when the outdoor heat-exchange temperature Tc at the present time drops to or more than a specified difference from a reference outdoor heat-exchange temperature Tcl at the time before the motor-operated expansion valve (5) is fully closed, when an indoor heat-exchange temperature Te at the present time rises to or above a specified temperature, or when a set time passes.

    Abstract: A receiver (4) is provided in a main line (9a) and a bypass passage (4a) having an open/shut-off valve (SV) is provided for introducing gas refrigerant in the receiver (4) into a low-pressure liquid line. A motor-operated expansion valve (5) is fully closed, the open/shut-off valve (SV) is opened, and then defrosting operation is executed. At the initial stage of the defrosting operation, the open/shut-off valve (SV) is closed. When a discharge-pipe temperature Td drops to or below a specified temperature, the open/shut-off valve (SV) is closed. When the discharge-pipe temperature Td rises to or above a specified temperature, the motor-operated expansion valve (5) is once opened to a specified opening. When defrosting operation is completed, the open/shut-off valve (SV) is opened in a heating cycle and the motor-operated expansion valve (5) is gradually opened.

    Abstract: A transport refrigeration system including a refrigerant compressor which is alternatively driven by an internal combustion engine or an electric induction motor. The transport refrigeration system achieves and maintains a predetermined set point temperature in a served space by heating and cooling cycles. When additional heat is required during a heating cycle while the internal combustion engine is driving the compressor, capacitors are connected across the induction motor, to cause the motor to function as an induction generator and build up an output voltage. The output voltage is monitored, and when it is sufficient to sustain a load, resistors located to aid the heating cycle are connected to receive the output voltage.
